Abstract: A higher forgery prevention effect is realized. A display includes a first interface section provided with a relief-type diffraction grating constituted by a plurality of grooves, and a second interface section provided with a plurality of recesses or projections arranged two-dimensionally at a center-to-center distance smaller than the minimum center-to-center distance of the plural grooves, and each having a forward tapered shape.

Abstract: A display includes a substrate with a light-transmitting property, a relief structure-forming layer disposed on at least one surface of the substrate and including a relief-structured region on a surface thereof opposite to its surface in contact with the substrate, a light-reflecting layer disposed on the surface of the relief structure-forming layer including the relief-structured region, and a printed layer formed on a surface of the substrate opposite to the surface on which the relief structure-forming layer is disposed, or between the relief structure-forming layer and the light-reflecting layer, or on a side of the light-reflecting layer opposite to its surface in contact with the relief structure-forming layer. The relief-structured region is constituted by recessed or protruding portions arranged two-dimensionally, has low reflectivity and low diffusibility under a normal illumination condition, and exhibits a diffracted light-emitting property under a specific condition.

Abstract translation: 显示器包括具有透光性的基板，设置在基板的至少一个表面上的浮雕结构形成层，并且在与其与基板接触的表面相对的表面上包括凸起结构区域，光 反射层，其设置在包括浮雕结构区域的浮雕结构形成层的表面上，以及形成在与设置有浮雕结构体形成层的表面相对的基板的表面上的印刷层，或者在 浮雕结构形成层和光反射层，或者在与反射层的与浮雕结构形成层接触的表面相对的一侧上。 浮雕结构区域由二维布置的凹陷或突出部分构成，在正常照明条件下具有低反射率和低扩散性，并且在特定条件下呈现衍射发光特性。
